The present invention relates to a device for the production of boxparts with inserted edge lining or neck.

' The prior art knows of various attempts made to combine in themanufacture of cardboard boxes the various steps of forming a part ofthebox from a cutting and of attaching the inserted edge lining or neck inone operation by plunging the upper die carrying the edge lining to beinserted into a drawing shaft in which the work is formed and,simultaneously, the walls of the box part are pressed against the gummededge lining or neck. However, it is impossible to insure a lasting andfirm connection of the various parts concerned even if the walls of thedrawing shaft are made elastic and the work on being combined with theneck is subjected to the spring-actuated pressure of the walls of thedrawing shaft. Moreover, the outputis unfavorably afiected in so far asa new neck can be attached only after the drawing step has beenfinished.

In one known device a composite upper die which is divided into twoparts is employed. One part of said die serves for forming the edgelining or neck which after being formed is moved to the second part ofsaid die and thereafter conveyed on said second part into the drawing'shaft. This composite die entails a complex arrangement for its controlsince the work has to be moved on the said die before it is in properposition for the drawing step.

The present invention ofiers a solution of the problem by placing theneck to be inserted in the known manner on an upper die or forming itthereon and leaving it in its original position, the upper die coactingwith a lower die which receives the cutting.

According to the invention, the cooperation of the two dies causes thepart of the box forming the bottom to be held between them underpressure, whereupon the laterally overlapping edges of the cutting arecaught by laterally engaging bending fingers and the like and thenfolded and pressed against the inserted neck; if necessary, specialpressers may be used for this step.

Several upper dies may be arranged on a common turret insuch a mannerthat during the combination of neck and the box portion to be formed theneck may be placed on another die or formed thereon while still anotherdie conveysthe finished work to a discharge shaft. I

Several embodiments of the invention are illustrated in the accompanyingdrawings, in which Figures 1 to 5, inclusive, represent a modificationof the device with bending fingers and pressers, Figs. 6 to 9,inclusive, a modification employing levers which serve simultaneously asbending fingers and pressers, and in which Figure 1 is a side view,partly in vertical section; Fig. 2, a special view of the pressercontrol; Figs. 3 and 4 represent the working dies and the parts relatingthereto in two diiferent positions and in vertical section; Fig. 5 is avertical sectional view of that part of the device where the finishedwork is delivered to the discharge shaft or channel; Figs. 6 to 8 arevertical longitudinal sections and partial side views of a modification,the working dies with the parts relating thereto being shown in threedifierent positions; and Fig. 9 is a diagram of the lower die with thebending or pressing levers arranged thereon.

Referring to thedrawings, the shaft 2, moves intermittently in anydesired manner, runs in the bearing 1 and carries at its end the turret3 within which the four, axially sliding dies 4, 4 4 and 4 are arranged,the bolts 5 being positioned in the guides 6 which do not permit anytwisting. The springs 7 hug the shoulder 8 of the bolts 5 and also theturret and tend to draw the dies 4 in a direction opposite to thedirection of the arrow in Fig. 1.

The gummed neck portion 6 is placed by any suitable device on one of thedies 4, the device being not shown as it does not form a feature of theinvention.

The receptacle 9 contains the box cuttings e which are continuallypressed against the slotted wall 12 by means of the-spiral spring 10 andthe plate 11. In the slot a slide 14 provided with a nose 13 is moved toand fro and removes at each stroke a box cutting from the receptacle.The cutting thus removed is guided by the plate 15 up to the stop 16 soas to be in front of the die 17.

At this moment the ram 43, influenced by suitable controlling meanswhich are not shownamoves in its uide 42 in the dire r tion of the arrowin r .flljfiflm oved ward against the i Sprin'gsfT. Simultaneously, thesesuppo'rting rod 18 is arranged in the guide 19 and controlled by therods 20, 21, 22 meves towards the die 4 so that the cutting 2 1s pressedin between the dies 17 and 4 ,rT en the bending fingers23 on the sleeve24 are moved forward a certain distance by the rods 25 and 26 to bendthe pieces 1', the extreme edges of which afe' now within reach of thepressers 27 which m'bv'forward concentrically and press the on to thegumined neck to be Before the pressers have completed their path, thebending fingers 23 must of-coiirse be drawn back.

'H'Dbe modification shown in Figs. 6 to 9 like the one just describedwith the-difierence, however, that the pressers 27 and their drivingmechanism have been disig 1 so that the or pensed with and the bendingfingers 23 have taken over the function of pressing the overlappingedges on to the neck portion to be inserted. The bending fingers areconstructed as toggles 51 and articulated to the die 17 at 47. On therod 18 a sliding piece 48 is ositioned and controlled by the rods 49,50.

he toggles 51 are connected with the sliding piece 48 by the rods 52 sothat, when the sliding piece moves in the direction of the arrow in Fig.6, the fingers bend the edge pieces of the cuttings (Fig. 7) and press213cm on to the inserted neck portion. (Fig.

The driving mechanism of the apparatus shown in Figs. 1-5 may comprisean electric motor or other prime mover 53. A driving pulley 53' on thedriving shaft of the motor is connected by means of a belt 54 with apulley 55 which is mounted on the main driving shaft 56 of the machine.Mounted on said driving shaft is a cam 57 on which roller 58 tracks. Thesaid roller 58 is connected to one end of a lever 59 which latter ispivoted intermediate its ends at 60. Its

free end of said lever 59 is connected to a rotatable lever 62 by a link61 which is pivotally connected to both levers 59 and 62. The saidswinging lever 62 is pivotally mounted at 63 to a portion of the machineframe. A link 64 joins swing lever 62 with slide 14. By use of saidabove described lever and linkage mechanism slide 14 may be reciprocallymoved by means of cam 58 on shaft 56.

A second cam 65 is also mounted on the main machine shaft 56 and aroller 66 mountedon a lever 67.,tracks the said cam. Said lever 67 ispivoted at the same point 60 at which lever 59 is pivoted. A link 68rotatably connected to lever 67. is also rotatably connected at 22 torod 22 intermediate its end. Rod 22 is pivotally mounted to a portion 69of the machine frame at 70. In this manner supporting rod 18 of die 17may be reciprocated.

A link 71 is pivotally joined to rod 22 at 22" and also torod 26 at 72.Rod 26 which through link 25 is connected to sleeve 24 is pivotallyattached to the machine frame at 73. By provision of link 71 sleeve 24is therefore given reciprocal motion by means of cam 65 which alsooperates supporting rod 18.

A further cam 74 is mounted on the main machine drive shaft 56 and aroller 75, rotatably mounted intermediate the ends of a lever 77, whichlatter is pivotally mounted to the machine at 76, tracks said cam. Lever77 is, connected to lever 80, which latter is pivoted at 81 to themachine frame through a link 78 connected pivotally at 77 and 7 9respectively to lever 77 and 80. Lever 80 at its upper end 80 is forkedto engage a bolt or pin 82 which is mounted on supporting rod 43 of theram 43. Reciprocal mo- Ilt tion of ram 43 is thereby effected from shaft56 by means of cam 74.

Also mounted on the main machine drive shaft 56 is a bevel gear 83,which latter meshes with a corresponding bevel gear 85. The latter issupported or mounted to a shaft 8a which in turn is supported in bearing86 attached to or forming part of the machine frame. Shaft 8% hasmounted thereon a spur gear 87 which latter meshes with a spur gear 88.The latter is supported on a shaft 89 suitably j ournaled to the machineframe. Shaft 89 has elements 90, 91 thereon which are adapted tocooperate with a Maltese cross 92 which latter is fixedly mounted toshaft 2. In this manner the turret 3 is driven step by step from shaft56.

The rod 34 (Fig. 2), which through link 97 is connected to a projection94 from ring 33, is actuated from shaft 56 by means of a cam 93connected on said shaft. A roller 95 rotatably borne on rod 34 trackssaid cam. Rod 3% is forked at its lower end and opposite arms 34 projecton opposite sides of shaft 56 serving as guides and preventing roller 95from leaving cam 93. With the above named mechanism the pressers 27 aremanipulated as described by periodic rotation of ring 33 throughactuation of rod 34 by cam 93.

In the case of the mechanism of the modification shown in Figs. 69, thedrive means for the presser 22, of course, is eliminated because thelatter themselves are eliminated. The rod 50 which serves to manipulatethe sliding base 48 of the pressing fingers 51 is driven from the mainshaft 56 from a cam mounted thereon by means of lever and linkagemechanism similar to that described for elements of the machine ofFig. 1. The other driving elements for other parts of the machine remainthe same as in Fig. 1.

The particular shapes of the cams form no part of the present inventionand are mere, matter of design. They must be so shaped and positioned onshaft 56 as to afford proper timing of the various elements of themachine.
